Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing ramp systems use fixed attachment methods, then installation is simple, but versatility and adaptability to various structures are limited

Engineering Contradiction:

Improveadaptability to various structuresVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ramp system is divided into multiple detachable components including a horizontal component, vertical component, and ramp component that can be assembled and disassembled. This segmentation allows the system to adapt to various structures while maintaining manageable complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment components are designed with universal features that can attach to different structures such as buildings, vehicles, and containers. The horizontal component with lip engagement and vertical component with hook mechanisms provide multi-functional attachment capabilities across diverse applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If existing ramp systems use fixed angle design, then manufacturing is simple, but adjustability to different terrain conditions is poor

Engineering Contradiction:

Improveadjustability to terrain conditionsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The ramp system incorporates adjustable angle mechanisms that allow the ramp component to be positioned at different angles relative to the horizontal component. This dynamic adjustability enables adaptation to various terrain conditions while using standard manufacturing processes for each component.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows change in the angular parameter of the ramp relative to the horizontal surface through adjustable connection points and pivot mechanisms. This enables the same manufactured components to achieve different operational parameters based on terrain requirements.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If existing ramp systems lack modular design, then structure is simple, but secure positioning and stability are insufficient

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vertical component acts as an intermediary element connecting the horizontal component to the ramp component. This intermediary provides stable positioning and secure attachment while distributing mechanical loads across multiple connection points, enhancing overall system reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If existing ramp systems use non-modular design, then assembly is simple, but adaptability to different structures is limited

Engineering Contradiction:

AI summary

A ramp system which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.
